*grumble, grumble* I was looking around at some of my sims and some ideas and noticed an error which I should have noticed earlier since the number of shells I entered just seemed off for some reason. I have no idea what I was doing when I calculated the total weight of the magazines because for 515 tons of 25mm ammunition is good for 25400 rounds per gun... which seems a bit extreme for those guns as it will take ~2 hours of almost continuous fire+several barrel changes to spend all that.
5" => 500 rpg = 122 tons
75mm => 1500 rpg = 214 tons
40mm => 2000 rpg = 262 tons
25mm => 3000 rpg = 515 tons
Total magazine weight: 1113 tons = 1990 rounds
Should be
5" => 500 rpg = 122 tons
75mm => 1500 rpg = 160 tons
40mm => 2000 rpg = 160 tons
25mm => 3000 rpg = 61 tons
Total magazine weight: 504 tons = 901 rounds
I added a bit more range to get the light displacement back down to 52,000 tons...
